Jd dealer brought me a brand new 3520 today. While driving it it was really jerky almost thew me off a few times. Bucked like a wild horse and it almost tipped over a few times as well even with no load. i have had a tractor (27 horse) for some years and I never had that problem, was I doing something wrong or is it the tractor?? Anybosy else have this tractor?

eHydro or Power Reverser? If Power Reverser, what gear/range? And what task were you performing when it did that? (starting, stopping, turning, etc?...)

if e hydro - what is the stopping distance set at when you come off the pedal. It has a range 0-9 and default is 5 if it got set to stop short you may feel like the tractor is quite jerky - I know I did when I tested it out on the lot. played with this setting and the tractor behaved much better. Hope this helps - let us know how it is going. Also, are your rear wheels set wide or narrow?

Tip over? What do you mean? Are you on slopes? Do you have a load of dirt in the loader raised up high? Are the tires loaded yet? Is it Hydro or power reverser? If it is hydro, start out by setting the RPM's around 1500 and feather the pedals easy on and easy off.
I read your other post where you stated that your 27 HP tractor could easily do more. You also said that you stalled the machine out twice. Obviously you don't understand how to set the settings or the dealer didn't explain much. As you become more familiar with the machine, you'll feel more comfortable. Loadmatch will keep the engine from stalling (if hydro).

Samaras:
Having operated both John Deere and Kubota tractors, I think I understand your feelings. Let me comment a bit on each point:
1. I too feel more tippy on the mid chassis John Deere than on the Kubota's that I have driven, particularly when tipping sideways. I don't think the John Deere is really any more likely to tip over, but rather John Deere has chosen to put the seat up higher for visibility and when you are up higher, it feels more tippy. Now if the rear of the tractor was coming off the ground that is another thing. That simply means the tractor did not have enough rear ballast.
2. The jerkiness you also commented on may be due to the difference in pedal forces between the Kubota and John Deere. The Deere eHydro has much lower pedal forces and if you push the pedal with the same force that you use on your Kubota, then you will experience a jerk because the hydro is very responsive. As others have mentioned, the 3520 does have adjustable aggressiveness levels (similar to Kubota's GST) that allow you to increase or reduce the responsiveness.
Also, mention your experience to the dealer and have the dealer drive the tractor to make sure there isn't a problem.
An additional thought - What range gear were you operating in. I find that A range is best when digging in dirt. B range is a little two fast and will jerk you around when driving over rough ground.
3. If you stalled the 3520, then either the Load Match switch wasn't turned on, or the tractor has a problem. I have never been able to stall a John Deere with an eHydro. I have slipped all four wheels on concrete while pushing and lifting with the bucket. I even tried to stall it by yanking the throttle back to idle while doing this and I could not do it! If the Load Match switch is turned off, then yes this tractor will stall because the hydro in it is the exact same one used in the much heavier 4000 series and 110 TLB. The hydro has enough capacity to bring any 3000 series tractor to stall if Load Match isn't enabled.
Good luck on your future tractor direction!

Sounds like you were driving fast in rough/cambered conditions...
